MACHINE FOR CUTTING AND TRIMMING PAPER.

SPECIFICATION forming part of Letters Patent No. 480,111, dated August2, 1892.

Application filed July 22, 1891. Serial No. 400,355. (No model.)

To all whom it may concern.-

Be it known that I, JOHN J. MANNING, a citizen of the United States, anda resident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Machines forCutting and Trimming Paper; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure 1 is a side elevationof a machine constructed in accordance with my invention. Fig. 2 is anend View of the same. Fig. 3 is a longitudinal sectional view of therevolving cutter cylinder. Fig. 4 is a transverse sectional View of thesame.

Like letters of reference denote corresponding parts in all the figures.

This invention relates to appliances for winding, unwinding, trimming,and cutting paper into strips of any desired width and length forprinting and other purposesfor example, narrow strips suitable forprinting telegraphic instruments, labels, and many other uses, orcutting card-board into strips of suitable width for railway and othertickets; and my invention consists in the novel construction andcombination of parts hereinafter fully described and claimed.

Referring to the accompanying two sheets of drawings, the letterAdesignates the frame of the machine, in one end of which are theadjustable boxes B for the shaft-and spool on which the roll of paper 0to be trimmed and cut into strips is wound.

In place of unwinding the paper from a roll, as shown and described, itmay be passed direct from the reel on the paper-making ma chine to thecutting-machine. The continu ous Web of paper, as it is unwound fromroll 0, passes over and between parallel guiderolls D and E, thefunction of which is to guide the'web of paper and hold it level duringthe process of trimming off the rough edges, a tension-roll F beingemployed to hold the web of paper steady and prevent it from vibratingwhile passing between the circular knives or cutters on thetrimming-shafts G and H.

These circular knives (shown at G and H) are fastened upon theirrespective shafts a suitable distance apart to trim off the rough edgesof the web of paper as it passes between them; but in case the paper hasbeen already trimmed on the paper-making machine then of course thesetrimmingknives may be dispensed with. The web of paper, aslit leaves thetrimmers and the guiderolls E, passes, as we have already seen, underthe tension-roll F and then up to the device for dividing the trimmedweb of paper longitudinallyinto strips of any desired width, and windingthese strips into rolls of suitable size for their respective uses.

' The dividing or cutting of the web of paper: longitudinally intocontinuous parallel strips of any desired width is performed by a seriesofcircular revolving knives or cutters I, placed concentrically andparallel to one another upon a threaded shaft J, as illustrated moreclearly in the enlarged detail View Fig. 3, the distance between thecutters being spaced or regulated by means of washers of suitablethickness K, which are interposed between them. The width or number ofthese spacing-washers will determine the width of the strips as theseare being cut by the revolving circular knives, and in order to permitof their ready removal, as well as the removal of the circular knives I,when required for sharpening or renewal, the shaft J is provided atopposite ends with flanged collars L, adapted to be placed upon theshaft so as to bear or bindwith their inner ends againstjthe outermostwashers K at each end. These collars L have flanges Z, against which theholding-nuts M may be screwed up tight on the threaded ends of theshaft, one on each side, so as to force the collars L with considerablepressure in the direction of the middle of the shaft, and thereby clampor bind the intervening series of knives and their interposed washersfirmly together, and thus cause the knives to revolve with the shaft.

Upon the end collars L revolve loosely the flanged idlers orguide-wheels N, the outside circular flanges a of. which project down onopposite edges of the paper as this, during the process of being cutinto strips, is wound into the roll 0, the paper being wound up to formthis roll during the process of cuttingc'. a, the edges of the circularknives I are brought into cutting contact with the web of paper duringthe process of winding it into the roll 0 as the roll gradually rises inits bearing, as hereinafter described.

A rapidly-revolving motion is imparted to the cutter-shaft J by means ofa bevel-pinion P at one end,which gears with anotherbevelpinion Q at theupper end of the drive-shaft R, as will more clearly appear on referenceto Figsl and 2. ShaftR is boxed in a movable arm or bearing S, the upperend of which also forms a box for one end of the revolving cutter-shaftJ, the other end of which is boxed in a movable arm T on the oppositeside of the machine. The arm T and its opposite corresponding bearing Sare both hung loosely at their lower ends upon a shaft U, which isjournaled in boxes in the outer ends of brackets V, forming parts of theside pieces of the frame. From this it will be seen that thecutter-shaft J, with its revolving circular cutters, is enabled to swingor move in the are of a circle having shaft U for its center, so as tobear with the sharp edges or peripheries of the circular knives againstthe periphery of the web of paper as it is being wound up to form theroll 0. Shaft U is revolved by the combination of gears clearly shown onthe drawings or by some equivalent arrangement of intermeshinggear-wheels or friction-pulleys, and revolves the adjustable drive-shaftR, through the intervention of the intermeshing pinions IV and X. Theroll of paper 0 as it is being formed is supported and rotated upon andby means of a pair of parallel horizontal cylinders g and g, journaledin boxes h and 7t in the frame of the machine. The winding-shaft 2'rests with its ends in a vertical slotted bearing j, (one on each sideof the machine,) to enable it to rise vertically as the roll of paper 0gradually increases in diameter.

Against the journals of the winding-shaft 'i bears at opposite ends aweighted lever 7c, the weight 7;, of which can be adjusted to regulatethe downward pressure of the lever upon the journals of shaft 2'. Theopposite or inner end of lever L is articulated by an arm m to thebracket V to give it a free motion and permit it to rise with thewinding-shaft t' in the vertical slotted bearing j.

In order to prevent the sharp edges of the circular cutters I frombecoming dulled by contact with the empty spools on which the strips ofpaper are wound up, in cases where iron or steel spools are used.cylinder 9 is provided with an overlapping hood or segment 1), asillustrated in Figs. 5 and 6, the ends of which, overlapping the ends ofthe cylinder, are journaled loosely upon the cylinder-shaft, so that thesegment 1) has a free swinging motion on the same. The end pieces ofthis segment are provided with brackets r, the outer ends of which formbearings for a roll 8, covered with lead or other suitable soft material that will not dull the edges of the circular knives when thesecome in contact with The segment 1), which carries this roll, is

provided on each side with a grooved pulley 25, around which and acorresponding grooved pulley u on a shaft 1; an endless band or rope 11;passes, there being one of these pulleys 'It at each end of shaft 4;, asclearly shown on Fig. 2. On the projecting outer end of shaft o is ahand-Wheel w for turning it.

From the foregoing description, taken in connection with the drawings,the operation of this machine will readily be understood. As the web ofpaper is gradually unwound from roll 0 it is first trimmed by passingbetween the revolving trimming-knives Gr and H and is then, afterpassing under the tension-roll F, carried to the spool or shell on thewinding-shaft This shaft, in starting the machine, is at the lower endof the slotted bearing 3', resting upon and between the peripheries ofthe revolving supporting-cylinders g and g, by frictional contact withwhich it is revolved and in the same direction. As the paper is woundaround this spool the roll gradually increases in bulk or diameter bythe accumulation of paper around it, causing the ends of theroller-shaft to rise gradually in the vertical slotted bearings on eachside, frictional contact between the roll of paper and therevolving-cylinders g and g, by which it is revolved, being maintainedand regulated by means of the levers 7t and their adjustable weights 7t.At the same time that the paper is being wound around the spool it issubjected to the action of the revolving cutters I, the shaft of whichrevolves at considerable velocity, so as to cut the paper into parallellongitudinal strips as roll 0 is being formed. The revolving cutters Iare caused to run perfectly true by the guide-flanges n of the idlers N,which slightly overlap the roll on both sides, and as the roll increasesin bulk and shaft 2 rises in its slotted bean in gs the revolvingcutter-shaft will rise with it, so as to always maintain cutting contactwith the periphery of the roll until all the paper on roll C has beenunwound, trimmed, cut into strips, and these strips wound upon spools orshells on the winding-shaft t'.

The object of the adjustable lead-coveredroll 3 is to supporter bedagainst the revolving cutters when the machine is first started, ifspools of iron or steel are used on the winding-shaft instead of spoolsof wood or other soft material. In that case by turning the hand-wheel wthe segment 2) is drawn over cylinder 9 so as to bring its roll 5underneath the revolving knives when the machine is started.

The horizontal supporting and revolving rolls or cylinders on which theroll 0 rests and by which it is revolved may be made of and covered withany suitable material, so as to maintain proper frictional contact withthe roll of paper and cause the same to revolve.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States-- ITO 1. The combination of the pairof supporting-cylinders, the Winding spool-shaft for the roll of paperto be wound upon, the movable segment overlapping one of thesupportingcylinders and provided with a roll of soft metal, andmechanism, substantially as described, for moving the segment and rollback and forth.

2. The combination, with the revolving cutter-shaft, of the circularcutters, the Washers or fillings between the same, the end collars,

clamping-n uts, and flanged guide-wheels or idlers running loosely onthe end collars, substantially as described.

In testimony that I claim the foregoing as I 5 my own I have hereuntoaffixed my signature in presence of two witnesses.

JOHN J. MANNING.
